What are domains?

Domain names are the unique, human-readable web addresses of websites. Domains are made up of three parts: a top-level domain, a domain name and an optional subdomain.

Domain best practices
To maximize search engine-referred traffic, it is important to keep each of the following points in mind:

Domain names should be memorable
Create domain names that are short, easy to remember, easy to type, and easy to say. This is great for word-of-mouth advertising because those visitors will need to visit your domain directly.

Use broad keywords when possible
When you can include a keyword that helps make it obvious what your business does and yet keeping the domain name catchy, unique, and brand-friendly, do it. But, stay away from domain names that might be considered “keyword-rich” or “keyword-targeted”

Stay away from hyphens if you can
Domains that use of hyphens often correlate with spammy behavior and can decrease domain name readability and memorability. Because of that reason, generally, no more than one hyphen should be used if at all.

Moving domains
If a webmaster needs to move one domain to another, there are several important factors to consider, including setting up the redirects on a page-to-page basis so that pages are redirected to corresponding sub-folders and deep content pages on the new domain. Webmasters should avoid redirecting all pages from one domain to the homepage of another domain.
